Hey everyone, Wanted to take the time to introduce myself. I live in Canada. I just bought a house with a nice pond in it. I am no stranger to ponds in that my parents use to have one that I would clean and open every day. However, I am not an expert by any means ,this is why I am coming here to talk. I just cleaned my pond and opened it up for the season. It was clear. Now the water has gotten a little murky all of a sudden. It almost looks like light tea. I have 3 shubunkins and 1 koi in there. The koi is only 4 inches I am growing him nice and big. It bugs me that I cannot see my fish and the water is gross after all the work I put in. I do have a crazy pond pump in the pond with two filters in the filter box. I also have an oxygen machine with two ports that is putting oxygen in the pond for my fish not to mention the fountain as well.
